marked thereon, which form a part of this specification.

My invention relates to a combined hot air and steam bath cabinet, and has for its object to provide an apparatus of this class for the treatment of persons by artificial stimulation of the skin to eliminate impurities.

A further object is to provide an apparatus of the class mentioned, wherein free air shall be purified before its entrance into the cabinet; and a further object is to provide.

means for purifying the air which has received the impurities'exhaled by the ,body.

. These objects are attained by the construction herein described and illustrated in the accompanying drawings, which show a preferred but not the sole embodiment of the invention.

In the said drawings ;Figure I is a side elevation of a closed cabinet constructed according to my invention.

vertical longitudinal section, and the cabinet cover removed, in section. Fig. III is an end elevation looking toward the foot of the cabinet. Fig. IV is a detail view of one of thecabinet cover pivots. Fig. V is a transverse vertical section taken on line VV of Fig. II. Fig. VI is a top plan View of the generator.

Fig. VII isa central vertical section. of the air induction device. Fig. VIII is a horizontal section of said generator near the .to thereof. Fig. IX is a transverse vertica section on line IXIX of Fig. VI.. Fig. X isa similarsection on ,lines X-X of Fig. VI. Fig. XI is a vertical section of the generator, on line XIXI of Fig. VIQ Fig. XII is an' elevational view of the corrugated inter-wall of the generator drum, the. outer wall being removed. 1, 2 designates the main frame, comprising the leg standards 1 and the connecting bars Fig. II showsthe. heating apparatus in elevation, the bed in plates 18.

2. Mounted within this frame is a rectangular stationary frame 3, made of either Wood or metal. strips 4, Within the frame 3, is a mat-tress frame 5, holding a mattress 6. The mattress frame may be canted as shown in Fig. I, for the comfort of the patient, its upper end Mounted revolubly on resting on the head rail of the bed frame.

Frame 3 also contains'a drawer 7, which is a convenient receptacle for sheets and for the patients valuables. Rising from the foot of the frame 3 is an upright plate 8 which supports a metal casing 20.

- 9 is a cabinet top or cover, made of rigid material and mounted on frame bars 2. At-

tached to one end of cover 9, by buttons 9 is a depending flap or curtain 9 that reaches to or below the mattresslevel. the opposite edge of the cover 9 is an oilcloth hood 10, adapted to cover the upper part of the patients body. To facilitate removal of the cover 9 it is provided with antifriction rollers 11, adapted to roll upon the anglebar edges of outerframe 3. It is also provided with hooks 12 adapted to engagepivot' studs 13, secured to the posts 1 as clearly seen in Fig. IV. When the cover 9 is retracted the hooks 12-strike the pivots13, .and the'coveris lowered to the floor Where it assumes the position shown in Fig. II.

14 designates an air induction device comprising a plurality of super-posed frustoconical members 14, the upper of which. is secured to an upwardly extending flue .15 that enters the bottom ofthe'generator-casing 19. Members 14 are connected together by hangers 16, and have central openings 14'. I

17 designates a shelf, forming the bottom of the generator casing 19 and secured to the walls of said casing. Plate 8 forms the back of said casing, and half of the sides a is formed by metal plates =18.' The remainder of the sides, also the front of the casing, is formed by a sheet metal plate 20, covered externally with asbestos or the llke 20', except where its edges lap those of 21 designates the fire shell of the steam generator, and 22, the water. shell thereof, which latter is provided with a drain pipe 22",.having a cook 22": The fire shell 22 tapers upwardly to a circular outlet 23. Its bottom is joined'to the bottom of the water shell, water tight, by a plate'22'. The bot- Attached to i tom of the fire shell is open. Said shell is pierced by two or more water tubes,'23'.

Connected into the head of the shell 22 are the steam outlets 24, the upper ends of which are bent forwardly and provided with plugs 25 whereby the discharge of steam into the cabinet may .be partially controlled. The hot air outlet pipe 26 is also, bent forwardly and is provided with a manually adjustable damper 27. Theledge I7 is covered by a layer of heat-insulating material 17 f The bottom of the generator 2l22 is spaced above the horizontal plate tom of said space are open, as shown in Fig. l

X, thus permitting heated air and gases to ascend freely between the generator and its outer casing.

30 designates a burner, that is adapted to maintain a high flame, andis set directly beneath the flue l5.

The operation of the apparatus is substantially as follows :-Water having been placed in the watershell 22 (as indicated in Fig. IX fuel is admitted to the burner 30 and ignited. The flame extends well up into the fire shell 21 heating the water the-rein, While heated air issues into the cabinet through the orifice of tube26. The patient, preferably stripped, reclines on the mattress 6.

The attendantplaces the cover 9 uponthe y frame and-arranges the hood 10 over the up per part of the-patients body leaving the head uncovered. When the water reaches a suflicient temperature, steam is generated and issues from the orifices of tubes 24 into the cabinet. The therapeutic effects of steam or moist heat upon the skin are well known.

Combustion is rendered more perfect by the oxygen, of the air that enters flue 1-5 between the parts 14. The airv within the cabinet following thelaws of convection and gravity, circulates by entering the lateral openings 28- and issuing from the orifice of tube 26. In

so doing it passes through the flame in shell 21 which consumes the impurities which as e alations from the patients skin have charged theain, 7 Any part of a patients body that may require higher temperature may be elevated above the other parts, as the temperature increases toward the top of the cabinet.

The plate 20 will of course become heated, and some heat will be radiated into the cabinet from this and adjacent metallic parts.

The relative humidity within the cabinet may be varied, also the quantity of hot air issuing from pipe 26 regulated, by adjusting the damper 27.

' The length of a treatment wili'depend, of course, on the judgment ofthe practitioner or the attendant in the individual case.
